A science experiment is like a recipe
What can two such different processes possibly have in common?One in the laboratory, the other in the kitchen. If you think about it you will agree that conducting a science experiment is rather like following a food recipe.
Both include step by step directions on how to proceed and both can turn into perfect disasters if you ignore some key instructions. Also both can be tweaked to get slightly different results from the original.
At the same time you can be literally playing with fire if you mess up with either. The key to a good outcome in either an experiment or a recipe is the preparation time that you spend on them before you actually get down to doing the deed.
Just as it helps speed up the cooking process if you wash and chop your ingredients in advance, it can speed up your experiment process if you have all the material required lined up and easily available to you.
To master a recipe you need to cook it repeatedly, in the same manner most scientific norms advice that any science experiment should provide the same outcome at least three times for it to be considered stable.
So when you get down to the basics you will agree that any science experiment you conduct can actually be treated at par with a new recipe that you want to try out.
